Can scissors float on water? Light objects are pushed back to the surface by an object’s upthrust. If the item is too heavy, the upthrust will not be strong enough to push it up, causing it to sink. For example, many children noted that the scissors are made of metal and the metal is heavy, […]
What is the energy obtained from Earth called?
What is the energy obtained from Earth called? Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. How is energy from the volcanoes generate electricity? Geothermal energy uses the […]
What is the phase shift?
What is the phase shift? The Phase Shift is how far the function is shifted horizontally from the usual position. The Vertical Shift is how far the function is shifted vertically from the usual position. How do you find the vertical shift of a trig function? Step 1: Remember the general form of a trig […]
Why did America not go metric?
Why did America not go metric? The biggest reasons the U.S. hasn’t adopted the metric system are simply time and money. When the Industrial Revolution began in the country, expensive manufacturing plants became a main source of American jobs and consumer products. Is Canada an imperial gallon? the imperial gallon (imp gal), defined as 4.54609 […]
Do microwaves only heat up water?
Do microwaves only heat up water? In summary: microwave ovens only really heat water (well), so yes they only heat the water in food; however, it doesn’t have to be liquid, it just absorbs more of the microwaves actually produced, causing liquid water to heat much more rapidly. Further more: yes absolutely your hand would […]
Does gravity affect aging?
Does gravity affect aging? There is no correlation between Gravity and aging. Aging is a process that is independent of Gravity. Gravity is a property of matter. Has more to do with atmospheric pressure than the effects of Gravity. Is gravity necessary for life? Gravity is very important to us. We could not live on […]
Is Crest and amplitude the same?
Is Crest and amplitude the same? The crest of a wave is the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position. The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. How do […]
What are the 6 steps of action potential?
What are the 6 steps of action potential? An action potential has several phases; hypopolarization, depolarization, overshoot, repolarization and hyperpolarization. Hypopolarization is the initial increase of the membrane potential to the value of the threshold potential. What are the 5 steps of an action potential? The action potential can be divided into five phases: the […]
Why does grass look green when you look at it?
Why does grass look green when you look at it? Why Grass Is Green? Like many plants, grass produces a pigment called chlorophyll. This bright pigment absorbs blue and red light, reflecting green light back to your eyes. Is grass really green? Like many plants, most species of grass produce a bright pigment called chlorophyll. […]
What is the relation between temperature and kinetic energy?
What is the relation between temperature and kinetic energy? Temperature is directly proportional to the average translational kinetic energy of molecules in an ideal gas. How do speed of molecules kinetic energy and temperature of matter affect each other? If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. […]
